joey1997,
Sorry to hear :( That can be such a pain. What happens when you try to drag the pieces exactly?
actually when i drag my pieces the peice goes to some place above and then when i move my peice to the square i want nd drop the mouse it says the move is illegal

I can not use provisional moves. The program claims they are illegal moves! Giganotosaurus
Can you give an example?
Everything on my screen except the game itself is to tiny for my old eyes to see. The windows methods of sizing, font changes etc. aren't active in the chess.com site. With my strongest readers I still can't make out the buttons. Is there a font size setting on chess.com?????
